Ꭺ PRACTICAL BUSINESS ARITHMETIC, FOR COMMON SCHOOLS AND ACADEMIES. INCLUDING A GREAT VARIETY OF PROMISCUOUS EXAMPLES. BY WHITMAN PECK, A.M., AUTHOR OF THE PROMISCUOUS EXERCISES IN ANDREW'S LATIN LESSONS Entered, according to Act of Congress, in the year 1868, by W. PECK, In the Clerk's Office of the District Court of the United States, for the H. C. STOOTHOFF, 39 and 41 Centre St., N. Y. PREFACE. 66 THE distinguishing feature of this Arithmetic, that which has chiefly led to its publication, is its containing, in addition to the examples under each rule, a large number of “ Promiscuous Examples" under several different rules. No two of these together being alike, pupils need to think how each one is to be done independently of another, instead of only doing all like one already done in the book, or by their teacher. They can often do page after page of examples as commonly arranged under their respective rules, though they could not do much simpler examples as they are apt to occur in practical business. Hence men often say, that their knowledge of Arithmetic, when they commenced business, consisted in little more than knowing how to add, subtract, multiply and divide, when directed to do so in an arithmetic, or by their teacher. This defect, it is believed, will be remedied by the repeated use of the promiscuous examples in this book. They are so classified and arranged that each "Exercise" requires the application of what has been previously studied in some portion of the book. The author having found such exercises almost indispensable in teaching arithmetic, has thought it would be a great convenience to teachers, to have an arithmetic containing a large number of promiscuous examples. Many experienced teachers, also, all with whom he has consulted, have confirmed him in this opinion. Hence, though there is perhaps too great a variety of arithmetics already in use, this is offered to the public. It is believed, too, that this arithmetic contains in one book, all the most important matter usually found in an arithmetical series, in which much the same matter is repeated in different books, thus greatly increasing the expense, without any real advantage. The first part, including the Fundamental Rules, is adapted to children beginning to study arithmetic after having received a little oral instruction; and they are advanced so gradually, that they will be apt to learn this part thoroughly before they reach Compound Numbers and Fractions 111900 |
